When the x or y doesn't change the distance is the absolute value (positive number) distance between the other coordinate. If you see that, the problem becomes quite simple.
\n" ); document.write( "The distance formula is sqrt{ ((x1-x2)^2+(y1-y2)^2}
\n" ); document.write( "For the first, sqrt{(0-0)^2+(5-8)^2}=sqrt (0+(-3)^2)=sqrt(9)=3
\n" ); document.write( "The first is just 8-5=3
\n" ); document.write( "The second is 7-2=5. If you do 2-7 and get -5, just take the absolute value which makes it +5.
\n" ); document.write( "sqrt((7-2)^2+(0-0)^2))=sqrt(25+0)=sqrt(25)=5. Distance is always positive.
\n" ); document.write( "The third is 14-9=5
\n" ); document.write( "The fourth is abs(1-11)=abs(-10) or 10.
\n" ); document.write( "The fifth is 3-(-2) or 5. Watch the sign. You can also look at that as going from -2 to 3, which is a distance of 5. \n" ); document.write( "

\n" );
